The regional rivalry between Iran and Saudi Arabia has pitted the two countries against one another in Lebanon, Syria and Iraq. But it is Yemen that has caused the two countries to escalate their war of words to unprecedented levels. When Saudi Arabia and its coalition of Arab countries began bombing Yemen in late March, they claimed they were targeting Houthi militias, which they accused of being supported by Iran. Checking Iran’s expansionist aims was one of the key talking points by the Saudi-led coalition.

However, Iranian officials and media have answered back. After Iran’s Supreme Leader Ayatollah Ali Khamenei's criticism of the Saudi bombing April 9, other Iranian officials have joined in. Comments by military officials have been some of the harshest.

At a security conference in Moscow on April 16, Hossein Dehghan, Iran’s defense minister, said, “The Saudi government, which undertook this military invasion with the help of America and Israel and intelligence help from some regional countries, not only will not achieve its own illegitimate goals, but has provided the grounds for its own collapse and irreparable failures and a similar fate of that of Saddam [Hussein] is awaiting it.”

He added, “The Saudi government should know that by supporting financially, logistically and by training of takfiris and terrorists in Syria, Iraq, Afghanistan, Central Asia and the Caucuses, and attacking Yemen while preventing humanitarian aid, will not turn it into an important country in the region.” Dehghan said that Saudi Arabia will become an important country in the region when it can unite Muslims and bring together the different sects, given that they are the custodian of the two holy mosques in Islam.
